WOOD, OF TORONTO, ONTARIO, CANADA, ASSIGNOR TO INTERNATIONAL BUSINESS MACHINES CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK TIME RECORDER Application filed November 17, 1927, Serial No. 233,978, and in Canada September 15, 1927.

My invention relates to workmens time recorders of the dial type in which the time sheet is carried by a cylindrical drum or platen and a time controlled printing carriage is adapted to move intermittently in a longitudinal direction across the time sheet and print the workmens time as they come and go, in columns representing the working periods into which each day is divided, the actual printing movement of the carriage into contact with the time sheet being effected by each Workman when he punches his number on the dial.

The divisions of the time sheet are varied to meet different requirements. The periods into which each work day is divided are in most instances Morning in, Morning out, Noon in, Noon out, Extra in Extra out so that each workmens time at the commencement of the days work is recorded in the Extra in and Extra out column.

.ship or relative setting of the parts be not disturbed during the operation of the recorder, otherwise a true record cannot be obtained. This is particularly true in respect of the escapement mechanism for controlling the intermittent movement of the carriage for this mechanism synchronizes the tabulating or intermittent movement of the carriage with the time element, and when it is disturbed the printed record on the time sheet iis entirely wrong.

Owing to these conditions considerable difiiculty has and still is being experienced with time recorders of this type, it being possible in the various recorder-s of this type heretofore used for the timekeeper or individual in charge of the recorder to unwittingly make a P. M. setting for morning requirements instead of an A. M. setting in which case the error is usually not discovered until the confused and almost unreadable record of the time sheet is noticed. Then again the relationship between the time elementand carriage was frequently disturbed during the normal operation of the machine causing further confused readings on the time sheet. This and many other minor troubles have been a source of constant trouble and expense and have so confused the pay sheets that heavy annual losses to employers have been the result. I

The present invention seeks to overcome these difficulties by providing a time recorder having the following salient features:

(a) A time controlled carriage whose movement intermittently in a longitudinal direction along the time sheet is so controlled by the time element that it is impos-' sible to disturb the columnar relationship of the carriage to the time sheet during the normal operation of the machine in so far as the work periods of each day are concerned. That is to say, if the carriage is opposite the Morning in column of say l/Vednesday in a weekly recorder it cannot, under normal conditions be moved to record in any other column than Morning in even though the carriage may be shifted manually to other days of the week. For abnormal conditions such as for instance When a workman has extended a work period beyond the allotted time and the carriage has been shifted forthe next period special mechanism is provided to move the carriage back to record the stopping time in the preceding period but this is only a temporary shift and the carriage automatically assumes its correct columnar position when the operation is completed.

(6) A general construction and arrangement of parts which permits of easy assembly and repair work and makes it possible to vary the capacity of the recorder. That is to say by a few minor replacements the capacity of a recorder may be increased from 50 employees to 100 or 150 as desired, or in like manner the capacity of the machine may be reduced.

In the past it has been necessary to construct three separate and dis inct sizes of machine to take care these different capacities. p

(c) Carriage suspension means movable vertically in unison with the carriage, which ensures a uniform distribution of stresses and strains resulting from the manual dial punching operation, and which may be readily adjusted to obtain a uniform printing pressure of the type wheels throughout the length of thetime sheet.

Other features will appear as the description progresses.

In the illustrated embodiment of the inven tion the recording mechanism is contained within a cabinet 2 having the usual fixed dial 3 on the front thereof bearing the worlnnens identifying numbers, and a manually operable lever f by which each workman is able to rotate the drum or platen to position in which his time will be printed on the time sheet in longitudinal alignment with his allotted number, the time sheetbearing num bers corresponding with those on the dial. These dial numbers serve as visible guides in the punching or recording operation, the workman in punching his time simply moving the lever 4 around the dial, on its central axis until the free end of the lever comes opposite his number, and then pressing the lever inwardly towards the dial a sufficient distance ding to my into cause the type Wheels hereinafter referred to to engage the time sheet, a circumferential series of spaced guiding openings 5 being formed in the dial opposite the numbers thereon for the purpose of receiving and guiding Jill 6 on the lever during thls operation.

The main supporting frame of the machine consists of unitary front and rear end frames 7 and 8 vertically disposed within the cabinet adjacent the front and rear walls thereof and fixed to the base of the cabinet at their lower ends as at 9, and horizontally disposed truss rods, 10, 11, l2, l3 and 1 extending between the end frames and having their ends mounted therein. The rod 1e braces the end frames at their extreme uppermost points while the other rods are arran ed in pairs located above below the drum platen and spaced equidistant-ly therefrom.

To facilitate assembly, adjustments, and repair work these truss rods 10, 11, L3 and 13 are simply passed through openings in the end frames and are secured therein by set screws 15, their front ends being extended through the front wall of the cabinet and car rying the dial 3, and the various other mechanisms are so constructed and arranged that in most insta-n es they may be assembled on the end frames before the latter are placed in the cabinet.

The drum platen, indicated 16, is of usual construction and is keyed upon a horizontal hollow shaft 1?, which is journalled in bearings 18 and 19 on the end frames, the front end of the shaft being extended through the front cabinet wall and having the bracket '20, which hingedly carries lever l, keyed thereon. llhe size of the platen will vary accordin to the capacity of the recorder. The end frames are consequently designed to permit the location of the platen shaft therein in three different positions indicated at A, B and C in Fig. 4, the shaft being located in the first mentioned position for the usual small size platen h-.. ng a capacity to take care of workmen, or in the second position when the machine has a capacity for 100 workmen, or in the third position when the machine is to take care of 150 workmen, these being the usual sizes in which recorders of this type are constructed. This arrai gement makes it possible to readily change the capacity of the machine with minimum disturbance and replacement of the parts and the cost of manufacture is consequently greatly reduced. In fact the construction and arrangement of parts throughout the machine has been developed with this desider atum in view so that the various parts common to all three types may be made in large quantities instead of having to be made in different sizes as has been the case in the past.

The time printing elements, which consist of the usual minute and hour type wheels 22 and 23, respectively, rotatively connected to the minute shaft 24 of the clock movement 25, and inking ribbon 26, are supported above theaplaten in a time-controlled carriage 27. This carriage automatically moves intermittently along the time sheet transversely to the day columns thereon A and its intermittent travel is synchronized with the clock movement through an escapcment 'mechanism hereinafter referred to. For details of the connection between the time wheels and printing wheels reference may be had to the Patent to R. Dey, No. 795,204, dated July 18 1905.

The carriage consists of a sleeve 28 slidable longitudinally along a horizontally disposed suspension rod 29, end frames 30 and 31 rigidly and detachably secured at their upper ends upon the sleeve between collars 32 and nuts 33, and an intermediate frame 33a mounted between the end frames adjacent their lower ends and carrying the ribbon in close proximity to the platen. These frame members are disposed transversely to and are located between the truss rods 10 and 11, and the frame 31 has lateral extensions 31a presenting straight vertical bearing faces 31?) which bear against these rods and thereby prevent lateral displacement of the carriage adjacent the printing point.

Automatic travel of the carriage in the normal direction is induced by a spring barrel 34 through a metal'tape 35 which passes over intermc iate pulleys 36 and 37 and is connected to a laterally projecting bracket 38 adjustable on sleeve 28.

The spring barrel contains a spiral spring 40 see Fig. 12) which is connected. at one end to the circumferential wall of the barrel and at its opposite end to the stationary part 41 of a two part shaft, the other shaft part being indicated at 42. This shaft is mounted in an auxiliary frame 43 supported on the truss rods 12 and. 13, and the shaft part 42 is rigidly connected to and adapted to rotate in unison withthe barrel relatively to the other part which is held against such rotation by a removable pin 44 passed through the frame, such last mentioned shaft part having a squared end 45 by which the spring may be wound up. The outer end of the shaft part 42 is rotatively connected to an indicator 46 which is moved in unison with the carriage, through the spring barrel and indicates the position of the carriage relatively to the divisions on the time sheet. These divisions 0n the embodiment illustrated consist of columns representing the days of the week, and subdivisions of each column representing the working periods of each day, the equivalent graduations appearing on the indicator dial.

The means for moving the carriage towards the drum or platen in the printing operation consists of a push-rod 50 extending through the drumshaft 17 and in operative engagement at its front end with lever 4 and at its rear end with one arm of a bell-crank lever 51 pivoted on the frame as at 52, the,

other arm of the lever being connected to the carriage suspension rod 29 through link 53.

The length of this link is adjustable so that; the vertical movement of the carriage maylower ends to pin 57 'pivotally connecting printing pressure of the type wheels on the. 1

time sheet throughout the length thereof the suspension rod has mounted thereon adjacent its ends rollers 60 and pinions 61, and fixed vertical guides 62 and racks 63 are mounted on the end frames on opposite sides of the rod, the rollers bearing against the guides and the pinions intermeshing with the racks. One of these racks may be adjusted vertically through screws 65 and 66 to vary printing pressure as desired, thereby making it possible to obtain a uniform printing pressure irrespective of the position of the carriage.

The escapcment mechanism which controls the intermittent feed of the carriage across the time sheet consists of a worm 70 mounted on the minute shaft 24 of ti o clock movement, a worm wheel 72 in intermeshing relation with the worm and keyed upon the lower end of a vertical shaft 73, a rotary escapeinent rack 74 keyed upon the upper end of such shaft, a toothed escapcment wheel 75 rotatable on shaft 76 and in intermeshing relation with the rack, a pulley 77 mounted on shaft 76 and rotatable in unison with said escapcment wheel in a counterclockwise direction, or independently of the, wheel in a clockwise direction, as viewed in Fig. 7, a ratchet wheel 7 S rotatable in unison with the pulley on the same shaft a pawl 78a carried by the escapcment wheel and adapted to engage the ratchet wheel, and metal tapes 79 and 80. Pulley 77 has two grooves and one end of tape 79 (see Fig. 9) is connected thereto in one groove as at 77 a and its opposite end is connected to a pin 81 slidably mounted in the carriage frame and encircled by a spring 82 which permits of a slightly rearward movement of the carriage relatively to the pulley for a purpose to be hereinafter explained. Tape (see 10) is other groove and extends upwardly over ing mechanism to the time mechanism; of an intermittently movable escapement means controlled by the time mechanism, carriage connecting means, and rotary means effecting an operative connection between the escapement means and carriage connecting means,

said rotary means being constructed andarranged to cause the carriage to move intermittently in one longitudinal direction in unison with the intermittent movement of the escapement means, and permit movement of the carriage in the reverse longitudinal direction independently of said escapement means, and manually operable means asso- 'ciated with said rotary means for releasing the carriage to permit it to move in thefirst mentioned direction independently of the escapement means.
